Brokers said the trading sentiment, mainly in banking and financial sector stocks, was dampened after RBI announced a slew of measures to curb rupee's volatility late last night, including hiking the lending rates for banks and sucking up of Rs 12,000 crore, to make the currency dearer.

This also raised concerns of RBI increasing interest rates in its first quarter monetary policy review later this month, they said, adding that a weakening trend in the overseas markets as German investor confidence unexpectedly dropped, also hit the trading sentiment.

Meanwhile, rupee appreciated by a hefty 68 paise to 59.21 against the dollar intraday today.
